But this is kind of a weird issue. If you are building with -m32 on an 64bit system you don't want/cannot have the run-backtrace-native-biarch.sh test. Since that tests 32-bit-on-64-bit. So this is really a configure issue that should notice that -m32 has already been added, so the test should be skipped. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread

There is some more discussion on what it would take to make 32bit processes handle 64bit processes on the same host. There is a WIP patch for ppc32-on-ppc64, but it is unclear if this can be extended to other arches. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread

Only a 64bit binary can backtrace a 32bit binary. So disable the biarch check that inserts -m64 for a 32bit host. https://sourceware.org/bugzilla/show_bug.cgi?id=24158 Signed-off-by: Mark Wielaard <mark@klomp.org> But lets keep this bug open. It would in theory be good if this worked. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
